Question

\(\frac{2001x2003+2003x2005}{2003x4006}\)tính nhanh

Answer 1

\(\frac{2001x2003+2003x2005}{2003x4006}=\frac{2003x\left(2001+2005\right)}{2003x4006}\)

\(=\frac{2003x4006}{2003x4006}=1\)

Answer 2

\(\frac{2001x2003+2003x2005}{2003x4006}\)

=\(\frac{2003x.\left(2001+2005\right)}{2003x4006}\)

=\(\frac{2003x.4006}{2003x.4006}\)

=\(\frac{1.1}{1.1}\)

=1
